"I actually made this recipe last year, but I made with blueberry, blackberry and strawberry. Make's for a lovely jam to use on toast, bread or scones.
I did heat the sugar in the microwave.
How many jars you get depends on the size of the jars.

Step 2

Preheat your oven to 100°C then place a small plate in the freezer.

Step 3

Cover a large baking tray with a sheet of baking paper. Spread the sugar on the tray and warm in the oven for 10 minutes.

Step 4

Meanwhile, place the berries, lemon juice, vinegar and 1/4 cup water in a large pan. Add the sugar, stirring over low heat until it fully dissolves. Increase heat until mixture is at a slow boil. When scum forms on the surface, remove with a slotted spoon. After 20 minutes, test to see if it has reached a set - place a spoonful onto a chilled plate and push mixture with your finger, if it wrinkles and a skin forms, then it's ready; if not, wash plate 9 in cold water) and return to freezer. Cook jam 10 minutes, then test again. Continue until jam reaches a set.
